My HP Laptop does have an Nvidia card but doesn't get much usage.
Got to figure out what is in it....since this is the first I have heard of this problem...
I have a hp tx1200 notebook, was a beautiful, good laptop, 8 months into ownership, it dropped wireless then it dropped video. HP replaced the motherboard underwarranty, that fix lasted 8 months or so and did it again. I barely got 2 years of service out of this laptop and I swore off hp for ever. I usta buy only hp’s. I know its not totally their fault but they should replace/fix these issues not say that you are reading blogs and they never heard of an issue with the tx1200. they cant help it when their suppliers screw them over but they sure as hell could help out their customers. I have bought to Asus’s now to replace my hp’s
